Games Like Incredibots: Physics Puzzles, Robot Building & Contraptions

Incredibots (Flash, 2009) was unique: 2D physics sandbox + programmable robot parts + puzzle goals. No single modern game clones it exactly, but these capture its DNA:

Physics Puzzle / Contraption

• The Incredible Machine / Contraption Maker — Rube Goldberg puzzles, official spiritual successor.
• Crayon Physics Deluxe — draw shapes that become rigid bodies; solve by creativity.
• World of Goo — structural goo towers; elegant physics + art.
• Portal 1 & 2 — momentum conservation puzzles, cooperative campaign.

Robot / Vehicle Engineering

• Kerbal Space Program — rocket/rover/spaceplane design, orbital mechanics.
• Robocraft — block-based robot combat, multiplayer.
• Scrap Mechanic — survival + creative vehicle/logic building.
• Besiege — medieval siege engines, steam logic, level challenges.

Automation & Systems (Late-Game Incredibots Feel)

• Factorio — belt/bot logistics, circuit network, massive scale.
• Satisfactory — 3D first-person factory, vehicles, exploration.
• Dyson Sphere Program — interstellar factory, mecha combat.

Pure Logic / Programming Puzzles

• Human Resource Machine / 7 Billion Humans — visual assembly coding.
• TIS-100 / SHENZHEN I/O — assembly-like circuit programming.
• Zachtronics titles — Opus Magnum, EXAPUNKS.

Closest Single Match: Contraption Maker (Steam) — same "build a machine to solve X" loop with parts reminiscent of Incredibots' rods/motors.
